Deep Draw Depth & Process

How deep can you draw metal to form a deep drawn can, shell, or cylinder? Professor Metal provides guidelines for deep draw depth, noting the limits for single draws and the importance of material selection.

ROUND SHELLS: Approximately 40% of the blank diameter can be drawn into one operation with one set of tools, i.e. 10" diameter blank can be drawn to 6" diameter in one operation. This will result in a height of 2 ¾". See chart below right.

SQUARE SHELLS: They can be drawn from a round blank using the same percentages as for round shells resulting in approximately the same heights.

RECTANGULAR SHELLS: A rectangular shell may be drawn to an approximate height of 86% of its width.

NOTE: The percentage above are approximate and will vary, depending on: type of metal, alloy radii’, blank thickness, quality of material etc.

Why Do We Choose Amalco?

“Amalco offers a 'one-stop shop'. In the past, our combustion cones were shipped back and forth between several subcontractors to have them perform different production steps. Amalco performs each of these operations at one facility, thereby reducing our cone supplier base from three to one. Now, we coordinate inventory and communications with only one cone supplier, which saves us invaluable time and resources.”
